SPECIFICATION forming part of Letters Patent No. 378,997, dated March 6, 1888.

(No model.)

To all whom it may concern.-

Be it known that I, J UDSON A. BALDWIN, of Winooski, in the county of Ohittenden and State of Vermont, have invented certain new and useful Improvements in Window-Screens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in window-screens; and it consists in the combination of a screen with sliding box-like brackets or extensions, which are applied to and are extensible upon the ends of the screen,

each bracket being provided with guides, so as to cause them to move freely upon the screen, and with stops to limit their movement, all of which will be more fully described hereinafter.

The object of my invention is to produce a screen which is not only alike on both sides, but which is provided with extensible brackets, whereby the screen can be adapted to win- (lows of different widths.

Figure 1 is a side elevation of a windowscreen, partly in section, and showing the brackets in differentpositions in dotted lines. Fig. 2 is an edge view, also partly in section.

A represents an ordinary rectangular screen, having the top pieces, a, and end pieces, I);

and B, the brackets or extensions, which are applied to opposite ends thereof and are made adjustable back and forth upon the ends of the screen, so as to increase or decrease its length in the usual manner, and thus adapt the screen to fit windows of different widths. Each bracket forms a three-sided box, which is closed at its ends and which fits snugly against opposite sides of the screen-frame, so that no insects can crawl between the frame and the brackets and thus get access to the house. The outer closed ends of the brackets limit their inward movement upon the screen, and their outward movement is limited by the stops 0, which are made of cloth, leather, metal, or any other flexible substance, and

which prevent the brackets from becoming detached from the screen. When the brackets are moved inward, the stops double up between the ends of the frame and the outer ends of the brackets, and thus take up no appreciable room.

Upon opposite edges of the frame are recessed guiding-flanges D, which act as braces to the frame, and upon opposite ends of each bracket are formed the two guides G, which catch over opposite sides of the flanges, as shown in Fig. 2, and thus guide the brackets back and forth in their movements and prevent them from binding and sticking, as would otherwise be the case. When the brackets are moved outward to their full extent,these guides overlap the flanges, so that insects cannot crawl between the ends of the flanges and guides, as they otherwise would do, and thus get access to the house.

As the brackets are alike on both sides, the screen is the same on each side, and hence either side can be turned toward the room. These brackets are made very light, and can be made of wood, sheet-iron, or any other suit able material, and add but very little to the thickness of the'screen.

Owing to the fact that the brackets are simply light boxes, open only at their inner sides, they add but very little to the cost or the weight of the screen.

Having thus described my invent-ion, I claim The combination of the screen A, provided with top pieces, a, and end pieces, 12, with the closed box-like sliding brackets B, which snugly fit over the ends of the frame, and which are provided with the guides G, which catch over guiding-strips secured to the frame of the screen, and the flexible stops 0, which are secured to the ends of the screen-frames and the brackets, substantially as shown.

In testimony whereof I afflx my signature in presence of two witnesses.
